supported upon a hanger or support (1 in ama-nner to permit it to be moved into or out of contact with the leather ring cl, and a rotary motion is communicated to this wheel by the roll d and the leather ring when it is moved and held somewhat forcibly against the same. The wheel d has a pinion dlwhich meshes with the gear d upon the shaft D, as shown in Figs. 1 and 2. To rotate the camshaft, the wheel (1 is moved into contact with the roll cl. The hanger d is hung at its upper end on the cam-shaft D, the wheel is journaled in the hanger about midway its length, and the lower end of the hanger is extended laterally to provide wings for a slot (1 by which and a headed steadypin (Z the lower end of the hanger is held in place and permitted to swing. A spring d serves to draw the hanger obliquely downward and the wheel (1 into forcible contact with the roll d. The hanger is moved upward to remove the wheel (1 from the roll (1' and held in its removed position by means of a cam-latch (Z pivoted on the stud (i having the long operating-handle d and acting against a projection 01 This projection preferably is adjustably secured in the slot d of the hanger.

The cam-shaft D carriesa cam F for oscillating the hanger b, the saw B, and the edgeturning devices B. This oscillating movementis comm unicated to the hanger by means of a lever or arm f, (see Fig. 5,) attached at its upper end to the hanger and bearing at its lower end a cam-roll entering the camgroove of the cam. The hanger is carried upon a horizontal shaft or long pivot f, which has bearings at f f in the frame, the pivot turning in its bearings and the hanger being clamped to the pivot by means of a split bearing or box f and a clamping bolt or screw f Figs. 1 and 3. By thus attaching the hanger to the pivot or shaft I am enabled to adjust it, together with the devices it carries, longitudinally in relation to the raceway and chucks. The shaft D also carries the cam G for operating the feed-dogs and the cams H II for operating the chucks. (See Fig. 4.) Before describing the connections between these cams and the things they actuate I will briefly describe the raceways and the position which they occupy in relation to the blank-cutting saw and the blank-turnin g devices or saws.

As seen in Figs. 1, 3, 9, 10, 11, 12, 13, l-it, They are parallel with each other, are horizontal, and

are separated from each other by a space a little more than equal to the diameter of the cutting and finishing sawsgvhich are arranged between them at their inner ends. Each raceway has a rectangular passage h, Figs. 3 and 9, through which the bung-blank-formin g strip is fed.

The strip-feeding mechanism is represented as consisting of two feed-dogs g g of usual form, carried by a holder g one upon each side of the feedway, to project through slots therein, the dogs being so shaped as to engage the strip upon the forward movement of the holder g and to ride upon the strip upon its backward movement. The holder g is attached to the upper end of a quite powerful spring g which is secured at its lower end to a lever gfiwhich has movement upon a pivot 9 It will be understood, of course, that each raceway has its separate feeding dogs, but the cam G serves to operate both in alternate or successive order. This is accomplished by so arranging the levers g that their cam-pins g come into line with the cam projection 9 upon the cam G. (See Fig. '7.) A coil-spring g about the stead y-rod g Fig. 1, pivoted to the lever and extending through a hole in an upright of the frame, serves to maintain the cam-roll in contact with the cam projection g Fig. 15, and in the operation of this part of the device the cam projection coming in contact with the cam-roll causes the upper end of the lever g to be moved, and also operates the feed-dogs and their holder g and unless there should be some obstacle to prevent the feeding of the strip the holder g is moved as though positively attached to the lever; but in case there is any obstacle to prevent the movement of a blank-strip then while the lever g is positively moved the feed-dogs and their holder are not moved any further than the strip will permit them to be moved, the spring connection g permitting them to assume a stationary position during the continued movement of the lever. This prevents damage to the machine in case of accident or any irregular action. The strips are held in the raceways by detents 71", Figs. 10, 11, 12, and 13, which bear upon the upper edge of the strip, hold it down in the raceway, and also hold it against any backward action of the feed-dogs upon the strip. There is across thefeedway near each end a recess m, Figs. 9 and 13, into which the cutting-saw enters sufficiently to sever a blank from the end of the strip. By their engagement with the strips the feed-dogs act as they turn upon their pivots not only to feed the blank-strips to the cutting-saw, but also to remove the finished bungs from the chucks and a previously-sawed blank to a position to be seized by the chucks. There is always, therefore, a sawed blank in that section of the feedway in advance of the recess m, that is, between the end of the strip and the chuck. In order that the size of the blank may be determined, it is necessary that the strip I QC should be moved by the feed-dogs first against an end stop, and it is also necessary, after the blank has been severed, that it be removed from contact with the stop in order that it may be moved forward upon the next feeding movement of the strip, first to dislodge the finished bungs, and, second, to take its place in the chuck. To accomplish this, the raceway is slightly dropped or arranged upon a slightly lower level or lower section m. This provides a stop m against which the end of the strip is fed by the feed-dogs. (See Fig.

. 10.) After the cuttingsaw has operated to sever a blank from the end of the strip the blank is moved downward by the transferrer m" into the lower section m of the race or to the position shown inFig. 11. The chuck having returned to its original position with a finished bun g, the strip is again fed forward, comes into contact with the stop m and pushes the cut blank upon the finished bung, dislodging it from the chuck and causing the cut blank to take the place of the bung between the face-plates of the chuck, the blank being pushed against the rear stop m. (See Fig. 12.) The transferrer m is operated as hereinafter specified.

Each of the chucks O C has a faceplate or head-stock 0 carried at the inner end of its operative shaft 0', and the tail-stock or face-plate 0 carried by a head or block 0 in which it is adapted to be rotated. The faceplate also has a spring-operated clearer c, Fig. 4, for forcing the finished bung from the face-plate. In operation the bung-blank is moved between the two face-plates, they being then in a position to receive it at the end of the raceway, and they are so supported and actuated that, having received the blank, the face-plate is then moved against the blank to press it upon the plate 0 and the chuck is then moved sufficiently to move the blank into operative relation to the edge-turning saws or devices. To so operate the chuck or its face-plates, there is attached to the outer end of the shaft 0 a bent lever 0 Fig. 4. This bent lever is movable upon a pivot o and its horizontal arm 0 extends inwardly and carries a cam-roll 0 which bears upon the edge-cam H. This cam is shaped first to hold the face-plate 0 open or away from the face-plate c and it acts in opposition to the spring 0 a rod 0 and is connected with the upper end of the vertical portion of the lever 0 by a yoke piece 0 Fig. 9, the spring bearing against the upper end 0 of the yoke and the nut 0 at the lower end of the rod. After the blank has been fed into position between the face-plates the cam ll revolving permits the cam-roll to ride oif its radial surface 0 and this permits the spring 0 to move the face-plate a into contact with the bung-blank to force the bung-blank against the plate 0 and to move them both laterally in relation to the raceway a sufficient distance to remove the blank from the raceway into operative rod.

This spring is carried upon.

relation with the edge trimming devices. The head a supporting the rear plate, is connected with the lever e by means of a sliderod 0 and a spring 0, arranged between the lever and a nut e on the outer end of the The head 0 is free to slide a limited distance on the support 0 It will be understood, of course, that the chucks are substantially alike and that they are successively operated, the one by the cam H and the other by the cam H. To actuate the blank-transferrer of, Figs. 10, 11, 12, 13, and 16, Iemploy a bar 0, Figs. 2 and 3, represented as attached to the yoke 0 This bar has an incline 0 upon its upper edge, which operates,when it is moved in one direction upon a stud 0 secured to the transferrer m to lift the latter to the position represented in Fig. 2, that is, when the chucks are separated and in a position to receive the severed blank, and which bar 0, upon being removed from contact with the stud o permits the transferrer to fall or drop, carrying with it the severed blank to the position represented in Fig. 11.

The operation of the machine is as follows: The blank-strips are fed into the raceways and are advanced by the feed-dogs in successive order to the severing-saws and severed blanks are successively advanced by the uncut strip at the same time to the chucks and alternately operated upon by the edge-finishing devices. I prefer to use for an edgetrimming device a series of circular saws varying slightly in diameter from the outer one, which is the smallest, to the inner or largest one, and I also support said saws by means of a rigid backing-plate e. The chucks and chuck-holders are represented as having a slight angle in relation to the edge-finishing devices sutficient to provide the bungs with a tapered edge, but it will be understood, of course, that the chucks and their holders may bear any desired relation to the finishing devices for the purpose of varying the bevel or even forming straightedged or unbeveled bungs.

It will be observed that a collar X encircles the slide-rod at about the mid-length thereof, connects the lever with the chuck-slide c and comes into contact with the end X of the box in which the rod slides at the end of its forward movement. This stops the movement of the slide 0 and of the face-plate 0 the faceplate then being in line with the inner side of the raceway. The continued outward movement of the lever 0 then compresses the spring 0 and moves the other face-plate a past the outer side of the raceway, so that there is then a space of sufficient width between the two plates, or, more properly speaking, between the end of the throw-01f 0 Fig. 4, and the plate 0 for receiving the bung-blank. Upon the reverse movement of the chuck the rod 0 by the action of the lever 0 and the spring 0 is moved in a reverse direction, actuating the slide 0 and the face-plate o of the chuck. Movement, however, is not communicated to the slide 0 and the faceplate until the lever 0 is very nearly brought into contact with the collar X fast to the rod 0 the spring 0 holding the slide and face-plate for an instant or sufficiently long to permit the spindle or throw-off c to move the bungblank against it and the face-plate c. The throw-off c and face-plate c then move together toward the edge-turning devices until the stop or collar X comes into contact with the front face of the bearing X, when the face-plate becomes stationary, and a slight continued movement of the lever 0 and faceplate 0 forces the prongs of the plate 0 into the bung-blank.

The chuck is made adjustable to meet the wear of the turning-saws in the following way: The rod c screws into the slide 0 and this gives the slide a a horizontal adjustment in relation to stops or collars X X which of course varies the position of the spaces in which the face-plate 0 moves. The faceplate 0 is adjusted in the same way, namely, by screwing its shaft 0 into the grooved collar X which is carried by the lever 0 the faceplate being set out from the collar or moved toward it according as the shaft 0' is screwed into or from the collar. Both the shaft 0 and the rod 0 are held after adjustment by setnuts. The raceways are made adjustable laterally in relation to each other upon the frame to provide for the wear of the saws by means of suitable slots through which the bolts fastening them to the frame extend. (See Fig. 2.)

The raceways are detachably secured to the framework in order that they may he removed and others of different sizes substituted to produce variations in the size of the bungs. It is not essential that the bung-strip feed devices be always employed, as previouslyformed blanks maybe fed to the chucks and operated upon by the edge-turning saws alone, and I would here say that instead of providing the chucks with a movement toward and from the edge-turning devices they may be provided with opening and closing movements only and not with the transferring movement, and that the movement of the edge-turning devices may be increased sufficiently to cause them to traverse by the edge or edges of the blank or blanks as thus held.

I would also say that the edge-turning devices may be stationary and the transfer movements of the chuck or chucks be increased sufficiently to cause the blanks to be presented during such movement or movements to the action of the non -traversing edge-turning saws or devices.

It is known to me that in a machine forproducing corks a rotary severing-knife has been mounted in a vertical plane in connection with a finishing-knife, which is arranged in a horizontal plane, and in connection with a feed-table which is arranged 0bliquely to the plane of the holding and severing devices. It is mybelief,however,thatIam the first to provide a bung-producing machine in which the feedway is arranged at a right angle with the blank-holding devices, and in which the severing device is arranged vertically, transversely of, and at a right angle with the feedway, and the first to produce a bung-making machine in which the feedway is at a right angle with the blank-strip-holding devices and both the rotary blank-severing device and the rotary trimming or edge shaping and finishing devices are arranged in a vertical plane at a right angle with the feedway.
